Nice boats those, ride the chop very well.... got one myself! 
It looked good from the videos i've seen of it,i'm looking forward to getting to the lake and testing it out!
Collected this boat this afternoon (Nikko Sun Runner 27mhz),bought it from ebay,takes 6 c size batteries and a 9v 6LR61 in the boat and 6 AA in the handset,it's 1/20 scale,has an automatic bilge pump,also twin prop but don't have a clue to the speed or range of it!
It's missing the charger (model CA/5) and it's also missing the antenna for handset,can anyone help me locate replacements?
Does anyone know when this boat was made and any more info about it?
Here's a few pics....
